Benchmarking and improving Boost.Real

Boost.Real aims at providing a data-type that can represent all types of computable real numbers and provides the flexibility of performing arbitrary precision arithmetic, the user can always decide and control the amount of precision to be used for a calculation thus controlling the computational power used by the machine. I propose to benchmark the library and compare it against other similar libraries. There is a scope of optimization for Trigonometric functions and performance can be improved by a significant amount. I also plan for several other small optimizations
